The question remains whether the profit which the sale in fact produced should be considered of an income character, as having arisen from the carrying on of the National Bank's banking business. The loss the Queensland National Bank made, namely the amount by which the sale price to the National Bank had fallen short of recouping the old "bad debt", had been treated by Queensland National Bank as a trading loss and had been allowed under s. 51 as a deduction for income tax purposes. It was no doubt correctly so allowed, for the original advances in satisfaction of which the pastoral properties had been accepted were advances in the course of the banking business; they were advances of circulating capital, and therefore the shares into which the properties were converted were investments of circulating capital; so that what was recovered through the sale of the shares was circulating capital, and what ultimately was not recovered was a loss on revenue account just as any excess would have been an income profit: cf. Punjab Co-operative Bank Ltd., Amritsar v. Income Tax Commissioner, Lahore [1] ; Colonial Mutual Life Assurance Society Ltd. v. Federal Commissioner of Taxation [1] ; Australasian Catholic Assurance Co. Ltd. v. Federal Commissioner of Taxation [2] ; Commissioner of Taxation v. Commercial Banking Co. of Sydney [3] . But it does not at all follow that the National Bank should be considered to have taken over the Queensland National Bank's assets in the same character as that in which the Queensland National Bank had held them. Their character in the hands of the National Bank must depend on the nature of the purchase transaction: was it a transaction on capital account - for the purpose of adding to the profit-making structure of the National Bank - or was it a transaction forming part of the profit-earning activities within the structure. I have no doubt that it was the former. The National Bank when buying all the premises in which the Queensland National Bank had carried on its business must have had in mind that some would be likely to prove redundant sooner or later and would need to be sold, but they had to be bought at the time if the goal of stepping into the Queensland National Bank's shoes was to be pursued. In exactly the same way the shares had to be bought, even if ultimately they should be sold as no longer required, for otherwise the desired appearance of complete continuity of business, as well as the collateral advantages, would have to be foregone. Both that appearance and those advantages may be subsumed under the general head of goodwill, for their nature was of that kind. The purchase of the shares bore no resemblance to an investment of banking funds, made to earn income pending a need for their deployment in the making of advances and the like; it bore no resemblance to an investment by way of erecting a second or third line of defence against a time of stringency or emergency. It was an acquisition, not of the kind that might be repeated in the course of the profit-earning process, but made once and for all for the sake of enhancing, even if only for the time being, the profit-earning potential of the enterprise as a whole. Of course the shares would probably produce income directly; but dividends on them would form part of the National Bank's assessable income not as being profit from the carrying on of the banking business but simply as dividends, as income in their own right, just as rents from superfluous premises bought from the liquidator of the Queensland National Bank would be income in their own right. For the Commissioner some emphasis was placed upon the fact that during the period in which the shares were held by the National Bank that bank held shares in other companies also. In most cases, however, the acquisition was a result of sub-underwriting contracts; some of the companies were subsidiaries of the National Bank; some acquisitions reflected modern tendencies for banks to reach into wider financial activities than banking, e.g. into the hire-purchase business; and one shareholding (in the Western Queensland Pastoral Co. Ltd.) had come to the National Bank in circumstances resembling those in which the Queensland National Bank had acquired the shares in the pastoral company. The evidence about these holdings does not indicate to my mind that the National Bank was engaged in an undertaking of such a kind as to give the colour of income to the profit that was made on the pastoral company shares. The acquisition of those shares did not follow any pattern of investment that the National Bank had followed; it is to be accounted for solely as part and parcel of the take-over of the Queensland National Bank's whole undertaking, so that in respect of purpose it was, as I have suggested, akin to a purchase of goodwill rather than a purchase of property to be turned over in the course of business. As the purchase of the shares stood outside the course of the banking business, the sale of them likewise stands outside it. The profit from the sale was in my opinion a capital profit according to ordinary business concepts.
